| titleOfInvention | Process for the preparation of terephthalic acid |
| abstract | Terephthalic acid is prepared by oxidizing paraxylene and/or paratoluic acid with a molecular oxygen-containing gas in the liquid phase at 150*-220*C. in the substantial absence of a lower fatty acid or halogen compound and in the presence of a cobalt compound and a manganese compound, which are at least partially soluble in the reaction mixture, the sum total of cobalt and manganese calculated as metals, present in the total oxidation reaction mixture being in the amount of 0.005-0.5 percent by weight, the weight ratio, calculated as metals, of the cobalt and manganese being 99.8 : 2-20:80. |
